1.Understand the MPEG-TS Structure: MPEG-TS (MPEG Transport Stream) files consist of packets, typically 188 bytes in size. Each packet starts with a 4-byte header, which includes a sync byte (0x47). The packets contain various streams, such as audio, video, and metadata. ...
TS包Header的第一层，由TCIMSBF编码的前四个字段主导，如discontinuity_indicator和random_access_indicator，以及PCR和OPCR等，这些为节目管理和同步提供了基础。第二层至第四层的字段则深入揭示了如transport_private_data等特定信息的处理。关键的PSI（Program Specific Information）机制在TS流中起着导航...

实务精选里的模拟MPEG2-TS源是推模式的sourcefilter,但接的是DSNETWORK,在GEDIT里不能接avisplitter,会无法连接,如果直接接mpeg2decode也会抱错,原因是不是模拟MPEG2-TS源没有做音视频分离,所以不能直接接decode?? 如果就想做一个向模拟MPEG2-TS源的推模式sourcefliter因该还要注意什么??? 1楼2006-08-21 ...
MPEG-TS:MPEG-TS是MPEG-2传输流(MPEG-2 Transport Stream)的缩写,它是一种数字多媒体传输格式。MPEG-TS文件通常用于存储和传输音视频数据,例如在数字电视和网络视频中。 2. 结构 MP4:MP4文件的结构是基于固定的框架和盒子模型。它包含多个盒子,每个盒子包含一定的信息,例如视频、音频和其他类型的数据。 MPEG-TS:...
